Security Updates for Windows Defender (November 2023)

high Nessus Plugin ID 185900

Synopsis

An antimalware application installed on the remote host is affected by a privilege escalation vulnerability.

Description

The Malware Protection Engine version of Microsoft Windows Defender installed on the remote Windows host is prior to 4.18.23100.2009. It is, therefore, affected by a privilege escalation vulnerability. An authenticated attacker can exploit this to gain elevated privileges.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update Microsoft Defender version 4.18.23100.2009 to address this issue.
